DOOR AND LOCK THEREFOR.

Specification of Letters Patent.

Patented Dec. 14, 1920.

Application filed. December 27, 1917. Serial No. 209,057.,

T 0 all whom it may concern."

Be it known that we, ELMER B. STONE, and CHARLES E. JoHNsoN, each a citizen of the United States, and a resident of New Britain, in the county of Hartford and State of Connecticut, have invented a new and Improved Door and Look Therefor, of which the following is a specification.

Our invention relates more especially to the class of locks employed for securing doors and similar devices, and an object of our invention, among others, is to provide a removable lock that may be applied to different doors, and that may be readily applied to doors or similar devices especially constructed to receive it; and a further object of our invention is to so construct a lock that the door casing shall be rigidly united, whereby the bolt may not be surreptitiously disengaged from its keeper.

One form of device embodying our invention and in the construction and use of which the obj ect's herein set out, as well as others,

may be attained,is illustrated in the accompanying drawings, in which- Figure 1 is a face view of a door frame and door showing the latter locked in place with our improved lock.

Fig. 2 is asimilar view showing the lock case swung to one side to release the door.

Fig. 3 is a view in cross section through a portion of the door and frame showing our improved lock'secu'red thereto, the scale being enlarged.

Our improved look, while not confined to any particular use, is especially applicable in securing the doors of lockers, such as are provided in gymnasium's and similar places, and in which the lock cases are adaptedv to be removed from the lockers and employed metal it is important that they be strengthconstruction.

underlie the door frame and by reason of i this structure the door of the locker may be through the slot in position to engage the back of the frame, as shown in Figs-1 and 3, the plate being thus removably held in place.

A look case 16 is secured to the back faceof the lock plate within the edges of the dish-shaped structure and is provided with outturned flanges 17 to receive screws or other devices for securing the lock case to the lock plate in a manner common to lock An opening 18 is formed through the door 11 and of a shape and size approximately that of the lock case 16, so that the latter may be, readily passed through the opening, as shown in Fig. 3 of the drawings, in which position the lock will be held by means of its'bolt 19 "which, when thrown, passes behind the door as shown in Fig. 3 of the drawings. It will be seen that when the lock plate is thus secured to the door with the flange 13 engaging behind the door frame and the plate extending across the gap or crack between the edges of the frame and door, they will be so rigidly secured together that it will be impossible to spring-them apart sufiiciently to permit removal of the lock plate. The case 16 contains a slotted barrel 20 to receive keys preferably of the notched type and by means of which the bolt 19 may be operated in a manner that will be readily understood by those skilled in the art, such a mechanism being shown in our copending ap lication of Serial Number 97,316, filed May 13th, 1916, and from which copending application the present case has been divided out.

In accordance with the provisions of the patent statutes we have described the principles of operation of our invention, together with the device which we now consider to represent the best embodiment thereof; but we desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means.

Our invention, as hereinbefore mentioned, is peculiarly applicable to structures in which the lock may be removed from the door of one locker that may permanently contain articles to the door of another locker that is used to temporarily contain articles, as of wearing apparel, and in the drawings herein the frame and door of one of such lockers is represented in Fig. 1 while a like frame and door of a second locker is repre sented in Fig. 2.

It will be noted that our improved lock case is operatively detachably secured to the door frame, its use contemplating the removal of the look from one structure and its attachment to another structure, and tho principal advantages of the lock are present when so used.

We claim- 1. A portable lock plate for securing two members together and comprising a single rigid member having securing means at one edge to removably and independently secure said plate rigidly and firmly in place in the regular operation of the locking de vice and to prevent movement of said member when so secured, and means cooperating with said securing means for locking the other edge of said plate in position.

2. A portable lock plate for securing two.

members together and comprising a single rigid member having a projection rigidly secured at one edgeto removably and independently secure said end rigidly and firmly in place in the regular operation of the locking device and to prevent movement of Said member when so secured, and means cooperating with said projection for looking the other edge of said plate in position.

3. A door frame member, a door member, a portable lock plate comprising a single ri id member having securing means at one ecfige for removable attachment to one of said members to secure said edge firmly and rigidly. in place in the regular operation of said locking device before attachment of the other edge thereof to independently secure said edge against movement when so secured,s' aid arranged to extend across the joint between said members, and means cooperating with said securing means for locking said other edge of the plate in position on the other of said members.

4. A door frame, a door, a portable lock plate comprising a single rigid member having securing means at one edge for removable attachment to the door frame in the regular operation of the locking device and before attachment of the other edge thereof to the door, said securing means rigidly and firmly securing said edge against movement when so secured to independently secure said edge, said plate being arranged to extend across the joint between said door and frame, and means cooperating with said securing means for locking the other edge of said plate in position on said door.
